Purity assay for solvent sample (GC-FID, Karl Fischer and ICP-MS)
Determination of solvent purity by GC-FID technique and Karl Fischer titration and metal screening of the sample with ICP-MS technique. Solvent purity assay with GC-FID and Karl Fischer techniques. Purity assay is performed by analyzing the sample with GC-FID and comparing the area of the solvent signal to the combined area of all peaks. In the results the purity of the solvent sample is expressed in percentage (%). Karl Fischer titration determines the amount of water in the sample. ICP-MS technique provides information on the concentrations of metals in a sample. The measurement includes the following elements: Na, Mg, K, Ca, Li, Be, B, Al, Si, P, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Zr, Nb, Mo, Ag, Cd, In, Sn, Sb, Te, Cs, Ba, Hf, Hg, Tl, Pb, Bi, U. In the results, the elemental concentrations are expressed in unit mg/kg.
